One noticeable difference between the Pizza Expo and other trade shows we have attended is the open sharing of knowledge and the genuine desire to establish good relations, even among competitors. Every chef is an artist, and they all love what they do. Independent pizza stores across the US may normally be competitors; this week, however, they come together as fellow pizza enthusiasts. At first glance, it appears they only share knowledge with each other since they may not directly compete in the same area. Upon deeper observation, everyone here is working to make the best pizza they can, while helping others do the same.
